Impress the heck out of your friends in the car pool with the Aura Mobile BT, a Bluetooth enabled product that turns your mobile phone, PC or Mac (for VoIP calls), or cordless home phone into a conference phone. It easily picks up conversation in the backseat (so be careful) and has surprisingly good sound quality. The 3 watt amp and dual speakers ensure enough volume to fill a car or conference room. (With hands-free law in effect, I'm keeping mine in my car.)

There's no software to install and everything you'll need is included in the package, even the car charger. Echo and noise cancellation help keep the calls clear -- even better than on my cell phone. My only quibble is that it's clunky; even though it comes with a visor clip, it kept sliding off, so now I have it balanced in the cupholder.

Sells for $129 at Spracht, and is also available at Amazon..
